Triaxial Load Cell MTA400

The FUTEK MTA400 is a high-precision Triaxial Load Cell (three-axis force sensor) engineered for simultaneous measurement of forces in Fx, Fy, and Fz directions. Designed for applications demanding multi-axis force data — such as wind tunnel lift/drag, robotic reaction forces, flight controls, and actuator feedback — the MTA400 offers low mechanical crosstalk, robust overload protection, and reliable performance in a compact aluminum package.

Key Features & Benefits

3-Axis Force Measurement in One Sensor — measure forces in Fx, Fy, and Fz concurrently without needing multiple separate sensors.
Low Crosstalk — engineered to minimize interference between axes, improving measurement purity.
Good Overload Protection — safe overload up to 150% of rated output (RO) to protect the sensor under transient loads.
Rugged Construction & Aluminum Body — lightweight yet durable design for many engineering and test environments.
Connectorized Interface — 10-pin LEMO® receptacle (EGG.1B.310.CLL) for clean, reliable connections.
Wide Temperature & Environmental Range — operates from –60 °F to +200 °F (–51 to +93 °C), with compensated temperature range of 60-160 °F.
Ideal for Advanced Applications — perfect for wind tunnel force studies, flight control validation, robotic actuator reaction forces, and multi-axis instrumentation setups.

When specifying an MTA400, consider:

Your required force ranges in all three axes (Fx, Fy, Fz) to ensure you choose the correct variant
Mounting / fixture design to minimize off-axis loads and loading errors
Cable / connector routing and shielding considerations for EMI, noise, and signal integrity
Calibration needs (tension/compression, matching across axes, traceable certificates)
Environmental or temperature extremes — check sealing, thermal drift, and mechanical protection
